[Diagnostic criteria of diffuse Lewy body disease].

DLBD is also called Dementia with Lewy bodies(DLB) which was proposed by the consortium on DLB international workshop(CDLB) in 1995. CDLB criteria of clinical diagnosis contain progressive cognitive decline as a mandatory feature, and fluctuating cognition, recurrent visual hallucinations and parkinsonism as 3 core features. Supportive features include repeated falls, syncope, transient loss of consciousness, neuroleptic sensitivity, and systematized delusions. CDLB pathologic criteria include the presence of Lewy bodies as the only essential feature, and associated features included Lewy-related neurites, senile plaques, neurofibrillary tangles, and regional neuronal loss in the areas vulnerable to Parkinson's disease. Lewy bodies are counted and scored from 0 to 2 in 5 designated cortical areas. Total Lewy body score of 7-10 indicates DLBD.
